Groundwater moves quickly through very permeable bedrock or overburden, and slowly through clay or silt.
Some may have developed during periods of higher water table, others in periglacial conditions during which normally permeable bedrock would have been made impervious by permafrost, thus allowing flowing water to erode it.
